A Methodology of Pattern-Oriented Visual Parallel Programming and Its Interactive Supports

1.我们提出了一种可视化的语言，在面向对象的并行编程的抽象层次更高，可以有效地描述。由于视觉符号，固有的图形概念，如模式和架构可以在语言中有可理解的表示。我们提出了视觉模式的概念和基于此概念的编程方法。我们还设计了一个交互式的集成环境，用于使用/重用视觉模式。我们设计并实现了一个可视化语言环境KLIEG，它的主要特点如下：（1）在设计、编程和调试阶段都使用单一的符号。(2)提供了一个简单的图形用户界面，用于使用/重用的视觉模式，封装的对象组合的设计信息。(3)软件架构被表示为视觉模式的嵌套组合。任何级别中的每个视觉模式都可以通过简单的图形用户界面进行替换。(4)在显示程序的一部分时，环境可能会对应该被替换的对象施加更多的压力（为其分配更多的区域）。(5)对于可视模式中的每个漏洞，可以定义多个替代实现（6）可以使用自动动画化可视程序执行的可视跟踪器。

1. We have proposed a visual language, in which higher levels of abstractions for object-oriented parallel programming can be effectively described. Thanks to a visual notation, inherently diagrammatic concepts such as patterns and architectures can have comprehensible representations in the language.2. We have proposed the notion of visual pattern and a programming methodology based upon this notion. We have also designed an interactive and integrated environment for uses/reuses of visual patterns.3. We have designed and implemented a visual language environment KLIEG, whose major features areas follows :(1) A single notation is available in design, programming, and debugging phases.(2) A simple graphical user interface is provided for uses/reuses of visual patterns, which encapsulate design information of object compositions.(3) Software architectures are represented as nested compositions of visual patterns. Each visual pattern in any level is replaceable through a simple graphical user interface.(4) Upon displaying portions of a program, the environment may put more stresses on (allocate more area for) the objects that should be replaced.(5) For each hole in a visual pattern, multiple alternative implementations can be defined(6) A visual tracer that automatically animates visual program executions is available.
